Zero Networks, the cybersecurity company reclaiming microsegmentation to deliver on its promise, announced it raised $55 million in Series C funding. The funding round was led by Highland Europe, with participation from existing investors F2 Venture Capital, PICO Venture Partners, Venrock, and U.S. Venture Partners (USVP). And this brings Zero Networks’ total funding to over $100 million.
The funding round solidifies Zero Networks’ position at the forefront of the Era of the Defender – a shift in cybersecurity where the burden of effort no longer falls on defenders reacting to threats, but on attackers forced to confront proactive, identity- and network-driven controls.
Problem being addressed: While lateral movement remains a defining tactic in the majority of ransomware and supply chain attacks, the absence of microsegmentation leaves most organizations dangerously exposed. And traditional tools focus on the perimeter. But once breached, attackers can move freely, often undetected for days or weeks. This is precisely what Zero Networks was built to stop.
At the heart of Zero Networks’ approach is its radically simple microsegmentation solution. Although microsegmentation has long been hailed as the gold standard for stopping lateral movement, it has historically been viewed as too complex to implement and scale effectively. Zero Networks has changed that narrative with an agentless, automated solution that finally makes microsegmentation effective and effortless – an achievement validated by record-breaking growth in 2024 and consistent five-star customer reviews.
While Zero Networks leads with modern microsegmentation, the full suite of offerings also includes Zero Trust Network Access (ZTNA) and Identity Least Privilege solutions, available on a unified platform. And by anchoring enforcement in identity, Zero Networks’ patented, MFA-driven approach ensures least privilege access across all users, devices, and workloads, delivering zero trust that actually lives up to its name.
Momentum: Since the Series B, Zero Networks has tripled its customer base, doubled headcount, and experienced over 300% revenue growth, driven by growing enterprise urgency around stopping lateral movement and enforcing true zero trust controls.
How the funding will be used: This new funding round advances the company’s next phase of growth, including team expansion across sales and marketing, research and development, and customer support. Additionally, funding will be used to increase go-to-market investments in North America, EMEA, and APAC and support continued innovation in Zero Networks’ award-winning solutions.
New board member: Jacob Bernstein, Principal at Highland Europe, will join the company’s board of directors.
KEY QUOTES:
“Microsegmentation has long been the crown jewel of network defense; praised for its effectiveness but abandoned because of its complexity. This funding raise validates everything we’ve claimed since day one: that we can make segmentation simple, scalable, and powerful enough to contain ransomware and stop lateral movement at its source. It also opens up a massive opportunity for every network defender out there to stop playing catch-up and start taking control.”
Benny Lakunishok, CEO and Co-Founder of Zero Networks
“Cybersecurity’s most promising but often misunderstood tool is microsegmentation. This technique is essential to proactive zero trust architecture that prevents attacks by design rather than merely responding to them. Since the early days of evaluating Zero Networks, it was incredibly clear that their customers don’t just like Zero – they love it. This is a testament to everyone from the founding team to their most recent hires at all levels, hand-picked to serve Zero’s customers and build innovative solutions. I look forward to working closely with Zero Networks, a company that I believe is going to achieve phenomenal success and enormous outcomes for its customers.”
Jacob Bernstein, Principal at Highland Europe
